Answer: part a) both the tension and gravity vectors will be pointing downwards.
part b) the tension vector will be pointing upwards and the gravity will be pointing downwards.
Explanation:
part a) Since you are looking at the FBD for the steel cable here, the tension will be pointing downwards because the girder is hung from the cable which creates a downwards tension. Gravity will always point downwards, to the ground.
part b) Since you are looking at the FBD for the girder here, the tension will be pulled upwards because the cable is weighted which creates an upwards tension. Gravity will always point downwards, to the ground.
Sorry for the poor explanation, but hopefully this makes sense.
20 beats per second.
Explanation: 20 x 5 =100
Missing question:
"<span>What is his velocity? Please answer using two sig figs in m/s."
Solution
The relationship between velocity (v), space (S) and time (t) is
</span>
<span>The space covered by Harry is
</span>
<span>and so the velocity is
</span>

The correct answer is a blackhole.
A blackhole is the only object in which nothing, not even light can escape.
Hope this helps!
If the object has a lower density it will float and it if it has a higher density it will sink, different liquids may also be heavier or lighter causing a different outcome.
